Microlite and Lapis lazuli Specific Gravity
Another important criteria for qualitative analysis of gemstones is Microlite and Lapis lazuli Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Microlite and Lapis lazuli Optical Properties during the identification of gemstone. Specific gravity of Microlite is 2.50-3.00 whereas that of Lapis lazuli is 2.50-3.00.
